DENVER — Jason Marquis pitched eight innings for his major league-leading 11th win and Todd Helton's RBI double in the first provided Colorado's only run in the Rockies 1-0 win over the Nationals.

Fresh off making his first All-Star team, Marquis pitched out of bases-loaded jams in the seventh and eighth innings. Marquis (11-5), who allowed seven hits and struck out three, was coming off a two-hit shutout at Los Angeles on June 30.

Huston Street threw a perfect ninth for his 20th save in 21 chances.

Rookie Craig Stammen (1-4) went a season-high seven innings, giving up five hits and the one run.

Marquis tied the franchise record of 11 first-half wins, sharing the mark with Aaron Cook (2008) and Shawn Chacon (2003).

The Rockies scored their only run in the first when Helton's double into the gap in left-center brought home Clint Barmes.

PHILLIES 22, REDS 1: At Philadelphia, Chase Utley hit a three-run homer and Shane Victorino and Greg Dobbs had two-run shots during a 10-run first inning.

Cole Hamels (5-5) allowed one run and three hits in seven innings to earn his first win since shutting out the Los Angeles Dodgers on June 4.

The Phillies tied a club record for most runs in the first inning. They scored 10 three other times, most recently on June 2, 2002, against Montreal.

It was the most runs by Philadelphia since a 26-7 win over the New York Mets at Veterans Stadium on June 11, 1985. The 22 runs were the most in the 6-year history of Citizens Bank Park.

Johnny Cueto (8-5) retired just two batters, allowing nine runs and five hits. It was the shortest outing in the right-hander's 2-year career. Cueto had never allowed more than six earned runs in a game, and his ERA rose from 2.69 to 3.45.

Jayson Werth hit a grand slam off infielder Paul Janish in the eighth.

CUBS 4, BRAVES 2: At Chicago, Rookie Randy Wells won his fourth straight start and Derrek Lee homered as Chicago won for the sixth time in eight games.

Wells (4-3) gave up seven hits and two runs in six innings, including a homer to Nate McLouth. Kevin Gregg worked the ninth for his 15th save.

Jair Jurrjens (6-7) gave up four runs and seven hits in six innings, including Lee's 16th homer, a two-run shot in the first.
